Types Of 3D Modeling

Have you ever watched an animated film and wondered how people could create such impressive 3D characters? Or maybe you’ve thought about how interior designers can create lifelike renders of a building or space that isn’t even built yet.

The answer to both scenarios is 3D modeling. But, what exactly is 3D modeling? How many different disciplines utilize this art form? And how do you even go about creating a 3D model?

These are all valid questions, as the art of 3D modeling can seem complicated and elusive to those who have never done it. Whether you’re looking to learn this technique, or you’re just generally curious, we at Foyr have all the necessary information for you!

What is 3D Modeling?

3D modeling is the creation of digital, three-dimensional graphics. The art of 3D modeling is actually based in mathematics, and there are multiple techniques, workflows, and modeling software options to choose from. Thus, the creation of 3D models tends to be a more complex, time-consuming process.

What Are 3D Models Used For?

3D models can be used within a variety of fields. Some of the most common applications are:

  • Designing 3D characters for animated films and video games
  • Developing new products within fields like medicine and technology
  • Creating digitized 3D garments for the fashion industry
  • Modeling and rendering unbuilt spaces within the real estate industry

How Do You Create a 3D Model?

There are various techniques for creating a 3D model, which have evolved over time thanks to improvements in technology. Regardless of what industry you are using 3D modeling for, there are four main methods to choose from:
1. Primitive Modeling
2. Polygonal Modeling
3. Rational B-Spline Modeling
4. Non-Uniform Rational Basis Spline (NURBS)

In this post, we will walk you through these four types of 3D modeling, and also provide some alternate solutions if this process feels too complex for your creative needs.

Primitive Modeling

This type of 3D modeling mostly uses spheres, cubes and other variations of these two shapes to put together the desired shapes. It is called primitive because it is a very rudimentary form of 3D modeling, mainly created through the combination of different pre-existing shapes.

This kind of modeling generally utilizes basic Boolean processors to get the right shapes and outlines. Boolean operators are some of the most common ways of generating three-dimensional surfaces and shapes. Designers can combine two different shapes or subtract one shape from another to create a new object.

Polygonal Modeling

This type of 3D modeling is done by working with X, Y, and Z coordinates to define different shapes and surfaces, and then combining the different surfaces into one giant shape or model.

When designers use the polygonal modeling technique, they typically begin by creating a wire mesh in the desired shape – this requires good working knowledge of the polygonal mesh theory, which means that this type of modeling might be too complex for beginners.

The most common use of this type of 3D modeling is in scanline rendering, which looks at each row of the model to generate an overall shape.

Rational B-Spline Modeling

Rational B-Spline Modeling is the most common type of 3D modeling and also bases its technology on the combining and adjusting of geometric forms. Users begin by creating the dimensions of each shape, and these polygons can then be twisted and curved to get to achieve the desired form.

One of the main reasons for this method’s popularity is that is easy to learn and master. This means that it has found resonance among beginners and professionals alike, and it enables people with various backgrounds to create compelling and unique forms.

Non-Uniform Rational Basis Spline (NURBS)

This final type of 3D modeling we will explore is Non-Uniform Rational Basis Spline, or NURBS for short. This is a very popular method of 3D modeling due to its elegance, as it functions via a mathematical model that can be applied in a variety of scenarios to create realistic curves and surfaces.

The beauty of NURBS is that it can operate independently as an efficient program – meaning designers can rely on the technology itself to create realistic models – but it also welcomes human intervention and customization to add finishing touches to the model.

Alternate Solutions

As you can see, there are many methods and techniques to creating 3D models. Each type has its own benefits, and they can be used interchangeably according to the designer’s skillsets and project requirements.if you’d like to know more about interior design software to explore different types of modeling, check out our read on the best software used by modern-day professionals.

But, as you can also see, the 3D modeling process can be very complex and require knowledge of various software and mathematical theories. If you are a beginner in the world of creating 3D models, you might find it more helpful to work with and customize pre-existing models, instead of starting from scratch.

One tool that allows for this is Foyr Neo, a space planning, designing, and presenting software created with interior designers in mind.
